APPARATUS FOR THE TREATMENT OF YARN PACKAGES WITH FLUIDS,

. Application filed November 20, 1925. Serial No. 70,390.

These improvements relate to apparatus.

for the liquid treatment of yarn packages by the passing therethroughunder pressure of liquor with which they are to be treated, withsubsequent extraction from the said packages of surplus liquor lefttherein by the passing of air through such packages under pressure. Inthe term pressure is deemed to be included any pressure aboveatmospheric pressure or any pressure below atmospheric pressure, i. e.vacuum.

The improvements have for object a very simple and efi'ective apparatusby which a considerable quantity of yarn may be treated in a short timewithout unnecessary handling, the apparatus being found very suitablefor washing yarns wound on spools having a perforated yarn bearingsurface with subsequent extraction of wash water therefrom.

According to the improvements a rotary cavity plate is mounted upon ahorizontal axis in a liquor tank, with means for mountin g the yarnpackages on the cavity plate in such a manner that direct access fromthe tank to the cavity plate interior can only be I had through theyarns, and a liquor pump is arranged to pass liquor through the yarnsinto the cavity plate and back to the tank. A vacuum pump is alsoconnected to the cavity plate interior, so that liquidand air treatmentof the yarns may take place successively without removing the packagesfrom the cavity plate, and the rotation of the latter allows removal oftreated packages and the substitution therefor of fresh ones fortreatment as the cavity plate ro-- tates, nontime being lost by theplacing in position of fresh batches of yarn for treatment.

modifications will now be fully described with reference to theaccompaying drawings, wherein Figure 1 is a longitudinal section of oneform of the apparatus...

Figure 2 is a cross section of same taken on line 2-2 of Figure 1.

Figure 3 is a detail of a spindle showing The improvements in twoconvenientpump'of any ordinary known type and a a branch from such pipecommunicates with a rotary liquor pump 13, between which pump and theinterior of tank communication is established by the pipe 14. Valve isfitted upon the branch pipe.

Upon the hollow bearing is rotatably mounted the cavity plate 16 theinterior of which is hollow, having the bosses 17, the

plate being positioned upon the bearing 12 by the end flange 10 on oneside and the annular block 9 upon the other. In the bearing are formedcircumferentialorifices 18 givlng communication at any point in therotation of the plate 16, between the interior of the latter and theinterior of the bearing 12, thus rendering the interior of the cavityplate 16 open to the pump 13 and to the pipe 19 leading to the air pump.

The face of the cavity plate is formed with bosses 20 having tappedholes 21 to any convenient number each formed on a radius line of theplate, and adapted to receive the neck of a spindle 22 as shown in thedetail Figure 3, a quick screw thread being formed on the said neck. Thespindle has a circular base plate 23 fixed thereon and the body of thespindle may be hollow and perforated or it may be solid and fluted asshown in the detail Figure 3 and in broken section Figure 1. Upon thisspindle are mounted yarn packages 24the packages shown are wound uponflanged bobbins 25 with washers 26 placed between two adjacent flangeswhen the bobbins are in position on the spindle 22-and when a spindle isfilled the whole" may be put under compression by the nut 27 on thescrewed end 27Lto ensure a fluid tight joint between the said adjacentflanges.

The cavity plate 16 is fitted circumferentially with the toothed annulus28 forming a worm wheel which meshes with a worm 29, on a worm shaft 30driven in any convenient manner and at a conveniently slow speed.

Spindles t0 the desired number having been charged with bobbins, thecavity plate is rotated and as an orifice 21 comes to the highest pointa spindle is screwed thereinto, each orifice 21 being thus fitted with aspindle 23 as the cavity plate 16 rotates. hen the plate is fullycharged, or during the charging, the tank is filled with the wash waterup to the level 31 and the pump 13 started.

The water then circulates through the yarn packages 2 1 into the cavityplate 16 through the orifices 18 in the bearing 12 and thence to thepump 13 to be returned to the tank, this circulation being kept up aslong as necessary and reversed if desired. The washing being completethe pump 13 is stopped, and the water allowed to run to drain throughpipe 8. The air pump is then started and air is circulated by means ofpipe 19 through the yarns in a similar manner to that by which theliquor was passed through them. Whilst this extraction is proceeding,the cavity plate 16 is stopped. The extraction of surplus moisture beingcompleted, the vacuum pump is stopped and the cavity plate againrotated, each spindle being removed as it arrives at the highest pointand a fresh one substituted for treatment.

The cavity plate being charged thus with new spindles, fresh wash wateris led into the tank and the whole process repeated.

In the modification shown in Figures 4 and 5, the parts are the same asshown in the figures hereinbefore described and referred to, but withthis exception that the bearing 12 has two orifices with three chambersformed by the partitions 32 and 33, the pipe 11 also being divided bycorresponding partitions as shown. Further, the cavity plate 16 isformed with segmental chambers 3-1 with dividing walls 35 each segmentbeing open to the pipe chamber 36, or the further pipe chamber 37. asthe cavity plate 16 rotates, and each orifice 21 is formed in the frontwall of a segment 34. One of the pipe chambers, 37. communicates withthe liquor pump 13, another 36, communicates with the vacuum pump by wayof pipe 19. The liquor in the tank being filled up to level 38 only, andthe cavity plate rotating, it will be seen that for a little more thanhalf the circuit of the plate 16 the yarn packages 24. are being treatedw h liquor, but as they rise with the plate 16 each segment 34 becomesclosed to the liquor pump and open to the air pump through the pipechamber 36. Continued motion of the cavity plate brings any such segmentout of communication with the air pump and into a position where itssegment registers with the are 39 Figure 5, of the surface of pipe.Thus, the spindles will succe sively pass through liquor treatment andair treatment and ultimately arrive at a point where they can be removedand substituted by fresh ones, the treatment, and the rotation of thecavity plates thus being continuous.

Where any liquor employed, or the material washed out of the yarns, mayhave a corrosive action any parts in contact with the liquor may be ofnon-corrosive metal.

The liquor level in the modification of Figures 4 and 5 necessarily onlycomesto the level of the partition 32 of the bearing 12. The tank maytherefore be only the height as shown in Figure e at that end oppositeto the cavity plate, and a circular bearing plate 39 be rotatably fittedwithin the tank on a bearing 40. The said plate is slotted radially asshown at 41 in the detail Figure 6, and the screwed end 27 of a spindle23 will rest in a slot, being secured by friction therein by a nut 42screwed up tightly to bear against the plate 39. Except where the lengthof a spindle and its load of yarns make it advisable to use such an endsupporting plate it may be omitted.
